DistributionAustralia (Queensland)

Type locality: Peach Ck, Mcnwraith Ra., 19km ENE of Mt Croll (13°45', 143°19') FNEQ.  
TypesHolotype: QM J37040 (Queensland Museum), female 
DiagnosisDIAGNOSIS: S. occultus is a moderately spinose, mediumsized Saltuarius (maximum SVL 108mm). An extremely long, thin neck, a function of elongate neck vertebrae (Fig. lOa), mean % NUSVL 24.2; a series of enlarged, spinose tubercles fringing the regenerated tail; and three lumbar vertebrae (Fig. 12b) separate it from all its congeners. S. occultus resembles S. cornutus and S. salebrosus in having male pre-anal pores (Fig. 5a-c). These are not present in S. swaini (Fig. 5d). In S. occultus they are very pronounced, and form a raised cluster (vs not pronounced, only just visible without magnification, and flat) [from COUPER et al. 1993]. 
CommentType Species: Saltuarius occultus is the type species of the genus Orraya COUPER et al. 1993.

Abundance: only known from the type locality (Meiri et al. 2017). 
EtymologyETYMOLOGY: From the Latin - 'hidden' and so, difficult to find.
